二．形容词和副词比较级最高级的用法

1．形容词和副词的比较级用法：当两者人或者事物进行比较时，形容词和副词要用比较级，也就是—er形式，比较级常常用than来连接被比较的两个人或事物。如：Li Lei is taller than Wang Jun.。

2．形容词和副词的最高级用法：当三者或三者以上的人或事物进行比较时，形容词和副词要用最高级，也就是—est 形式，最高级之后常常用of ,in 等短语来限定比较的范围。如：Li Lei is the tallest of all /in our class。注意最高级之前一定要用the ,但副词之前可以省略。如：Li Lei runs (the ) fastest of the three。

good/well—better—best bad/badly—worse—worst little—less—least far—farther—farthest （注：常用的有五个many/much good/well little bad/badly far,可以这样记：多好与一点点坏相差很远）
